Title: Semiconductor switch
Inventor: OKUHARA SHINJI
IPC: H03K17/73
Filed: 1979-09-21
Abstract: PURPOSE:To enable to increase the capability by dV/dt of PNPN element, by connecting a diode between the base of a transistor the emitter of which is connected to one main terminal of the PNPN element and the layer adjacent to the main terminal. CONSTITUTION:The collector and the emitter of Tr12 are connected between the gate G and the cathode K of the PNPN switch 11, the emitter of the transistor Tr16 is connected to the anode of the switch 11 and the collector of Tr16 is connected to the base of Tr12. Further, a diode 17 is connected between the base of Tr16 and the layer adjacent to the anode A of the switch 11. With a DC voltage fed between the anode and the cathode of the switch 11, when the switch 11 is triggered by supplying a current to the gate G, the electric charge stored on the base of Tr16 flows to the anode gate of the switch 11 via the diode 17 to obtain the protection of dV/dt against the rise in the forward voltage applied next.

Title: Digital broadcast receiver
Inventor: TSUJISHITA MASAHIRO
IPC: H04J11/00
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To automatically correct a carrier deviation, caused when a received signal is converted to a lower frequency, in a short time by providing a control means connected to a data shift means and controls a shift quantity and a carrier deviation detecting means connected to a memory and decides the shift quantity of a carrier shift means as carrier deviation when a value stored in the memory reaches a maximum value. SOLUTION: A peak detecting means 14 detects a peak value by a maximum value detecting means 25 from the output of inverse FFT and stores it in the memory 26. A control means 19 shifts complex data in the carrier shift means by one carrier after the peak detecting means 14 finishes the process, and repeats the process up to the peak detecting means 14 as many times as specified. After the control means 19 finishes the process as many times as specified, a carrier deviation detecting means 14 detects the maximum value among peaks detected by the peak detecting means 14 and finds the carrier shift quantity of the carrier shift means 17 where the peak value is obtained. Then a voltage for correcting this carrier deviation is inputted to a voltage-controlled oscillator for tuning to a broadcast frequency.

Title: Magnetic switch circuit
Inventor: KAWABATA OSAMU
IPC: H03K17/80
Filed: 1993-05-24
Abstract: PURPOSE:To obtain the magnetic switch circuit executing the same switch operation for pulse voltages having a stepwise magnitude. CONSTITUTION:When the magnitude of a pulse voltage is changed stepwise by 1 or 1/2, for example, a ratio of magnetic flux effective cross sectional areas of iron cores 22, 23 is set to be 1:1. In the case of switching by a large pulse voltage, a bias voltage is applied to windings 25, 26 by bias power supplies 27, 28 operated by an external command to reset a magnetic flux density initial state of the iron cores 22, 23 to increase the magnetic flux saturation quantity of the entire magnetic switch circuit 21. In the case of switching with a small voltage, the magnetic flux density initial state of one of the iron cores 22, 23 is set to the saturation position and the entire magnetic flux saturation quantity is made to correspond thereto. Furthermore, in the case of corresponding to pulse voltage of the magnitude of 3 stages or more, the number of units is extended and made coincident with the stage number of the voltage. Thus, the same switching operation is realized independently of the magnitude of the pulse voltage.

IPC: C02F11/12
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To obtain a treated matter of a low chlorine content by subjecting a sludge to a pressurization treatment. SOLUTION: A small-sized ball mill device or the like of a hermetic structure is used to subject the sludge to the pressurization treatment. The pressure conditions are preferably set at >=1.2 atm. The pressurization treatment time is specified to >=15 minutes and the sludge temp. to 120 to 150 deg.C preferably for an improvement in destruction efficiency of microorganisms. As a result, the cell coals of the microorganisms in the sludge are destroyed in their shapes and a part of the cytoplasms contg. the chlorine compd. leak to the outside of the microorganism bodies. When the resultant treated matter is subjected to a dehydration treatment, the free water, interstitial water, capillary coupling water, etc., in the sludge are separated as filtrate, etc., from the solid content and the dehydration treated matter having a moisture content of 70 to 80% is obtd.  At this time, the cytoplasms contg. the chlorine compd. leaking outside the microorganism bodies are also separated from the solid content and, therefore, the resultant dehydration treated matter has the low chlorine content. The moisture content of the dehydration treated matter is preferably lowered down to about 5 to 15% by drying the treated matter.

Title: Directional coupler
Inventor: SUZUKI KAZUNARI
IPC: H01P5/18
Filed: 1987-05-19
Abstract: PURPOSE:To improve the coupling degree and to minimize the leakage of signal from the upper layer by adopting multi-layer structure for the coupling part and decreasing the coupling degree of the upper layer more than the coupling degree of the lower layer. CONSTITUTION:A dielectric layer 19 is provided further to the upper part of a coupling conductor layer 20 and coupling lines 18, 22 constituting the 2nd parallel lines are formed to the surface. The thickness d1 of the dielectric layer 21 is selected to be thinner than the thickness d2 of the layer 19. Both ends of the line 18 are connected to microstrip lines 8, 9 via connection conductors 12, 15. The line 22 is formed similarly. A conventional dielectric base is used as the dielectric layers 7, 19. In giving a wave to the line 8, the coupling between the lower side coupling lines 16, 17 is conducted via the conductor layer 20 and part of the wave is led to the upper coupling line by the conductor 12 and coupled between the lines 18, 22 via the conductor layer 20. In selecting the length of the parallel line to 1/4lambda, the coupled wave is not propagated to the line 10 but to the line 11. Since the relation of d1<d2 exists, the effect of the signal leakage from the upper layer is reduced.

Title: Gasket in metal
Inventor: TAKEDA HIROMITSU
IPC: C22C9/00
Filed: 1978-10-05
Abstract: PURPOSE: To obtain this gasket in metal that displays sufficient seal-up capacity, by applying the thermal elastic martensite transformation of a copper alloy containing 10W12wt% aluminum and 2W4wt% nickel.  
     CONSTITUTION: A copper alloy containing 10W12wt% aluminum and 2W4wt% nickel is melted in a vacuum melting furnace, and casted in fixed shape. The copper alloy has high, elastic deformation capacity, and the transformation again returns to the original constitution when removing load and transforms in the opposite direction with the return. Thus, the alloy shows large, elastic deformation as rubber though it is metal. Consequently, it can sufficiently resist large deformation being accompanied by high temperature baking treatment, and can keep high vacuums. Powerful clamping pressure can be applied because the copper alloy by this invention also has high elastic limits, thus ensuring high, close adhesion properties and concordance properties with the opposite flanges.
